Some are, some aren't. Google wanted me to assign copyright even for projects that I worked on entirely at home. There's an additional process you have to go through if you don't want to assign copyright. Personally I didn't care since it's under an unencumbered open source license anyway, so it hardly makes a difference.

(To be clear, I meant the good/evil thing to be tongue-in-cheek...)

That's... disturbing, and all the more reason to keep your work and private life strongly isolated. Suppose outside of work you write scripts for various things and distribute them online to friends and so forth, or blog posts, etc. Your employer should never be able to claim ownership of that.
